Sync function return value with hooks gets messed up somewhere in the call stack ?

[bojand]

With 0.3.2 and 0.2.1

var hooks = require('hooks');

function Doc(data) {
  this.name = data.name;
}

// Add hooks' methods: `hook`, `pre`, and `post`
for (var k in hooks) {
  Doc[k] = hooks[k];
}

Doc.prototype.foo = function() {
  console.log('foo');
  this.name = this.name.toUpperCase();
};

Doc.prototype.getBar = function() {
  console.log('bar');
  return 'bar';
};

Doc.pre('foo', function(next) {
  console.log('pre foo');
  next();
});

Doc.pre('getBar', function(next) {
  console.log('pre getBar');
  next();
});

var doc = new Doc({name: 'Joe'});

doc.foo(); // good
console.log(doc.getBar()); // prints return value of undefined
console.dir(doc); // { name: 'JOE' }

Output:

pre foo
foo
pre getBar
bar
undefined
{ name: 'JOE' }

Maybe I am doing something wrong...? Everything is executed correctly, but the return value ends up being undefined. Tried stepping through things and debugging it, not sure what happens. The return value is correct both in the ret in _done and in fnWrapper in once.

Your output looks ok, but with additional output 'undefined'.

The problem is you call doc.getBar() inside a console. But inside your doc.getBar() method there is another console.

Simply try this : console.log(console.log("JOE")); You will see it will print undefined.

doc.getBar() prints 'bar' and then returns 'bar'. so the return value should be printed.

ie.

function getBar() {
  console.log('bar');
  return 'bar';
}
console.log(getBar());

outputs:

bar
bar
